Some snake repellents are risky to use around people and pets because they use the active ingredient in mothballs, naphthalene. The United States Environmental Protection Agency (EPA) has classified naphthalene as a carcinogen that can cause damage to the liver, neurological issues, and cataracts. 

The Colorado State University Extension suggests there’s not enough conclusive evidence of the effectiveness of snake repellents to recommend their use.

Rats are nocturnal creatures, meaning they are most active at night, typically from late evening through the early morning. They use the cover of darkness to explore, forage for food, and find water, as they feel safer and can avoid daytime predators and human activity. Their sharp senses, including keen night vision and hearing, are well-suited for navigating in the dark. Because they prefer to stay hidden during the day in secluded areas like walls or attics, you are more likely to spot signs of their presence—such as droppings or gnaw marks—before you see an actual rat.

When baiting an iguana trap, several items should be avoided. Do not use poisonous baits, such as those intended for rats or mice. This practice is often illegal, is unlikely to attract iguanas, and poses a significant risk to pets or other wildlife. Additionally, avoid using herbs, fruits, and vegetables that are toxic to iguanas, such as fresh sage, rosemary, avocados, and eggplants. While ripe fruit can be an effective bait, be sure to remove any pits or seeds from fruits like apples, pears, and peaches, as they are highly toxic. Finally, steer clear of citrus fruits, which act as a natural deterrent.

Some plants that are toxic to animals or insects are also toxic to people. Daffodils, for example, are considered poisonous to humans (although they are rarely fatal). Most of the other plants listed above, however, are safe (and delicious!) for humans to eat, including basil, rosemary, and lemongrass.
